National Debt and Wars

Curated and Reviewed by Lesson Planet

Take a functional approach to the national debt. Learners collect information about the national debt by decade and plot the data. They determine whether an exponential curve is a good fit for the data by comparing the percent changes from one decade to the next. Working in groups, scholars compare changes in the debt during the Civil War, WWI, and WWII.
